To all whomit concem:

- Be it known that'l, WILLIAM H. Hoornn,

of Lynn, in. the countyof Essex and State of Massachusetts, and a citizen of the United Y tion, in connection with the accompanying drawings, is aspecification, like numerals on the'drawings representing like parts The inventionto be hereinafter described relates to channel. moistening devices-em'-' fastener inserting mac chine operation.

'ployed' in connection"with sole sewing or fastenln machmes 1n the manufacture of boots an shoes.

It has heretofore been proposed to provide some machines of this general character with devices for moistening the channel of boots and'shoes to facilitate the insertion .of the fastening means, but suclnlcviccs have either acted periodically or were started and stopped by the machine "stopping and start mg means. As well known by those skilled in the art, each of these devices, as thus pro posed, is open. to objection; the former on account of wear and tear incident to. its rapid movements and the power necessary for its operation, and the latter owing to the fact that the action of the nioistcning device was restrictedisolely to the periods 'ofma:

The present invention aims to overcome these and otherobjectionsincident to such" prior devices, and provide a moistening device which may' be throwninto action either withor without starting the sewing or other main continuously in o eration until after the machine has steppe and be thrown out of action 'bya reverse movement of such machine. v

In some types of sewing or'other fastener inserting machines it is desirable that the operating pa'rtsrbe brought to rest in predetermined position, as, for instance, with the needle raised, and that such action 'be' secured without shock.- In Such machines,

- after the ldrivingpower has been" disconnected, the momentum of. the moving arts" is utilized to'wi'ndup a spring, which t ere after acts to reverse the machine and bringit to restin' the-desired predetermined position, all as pointed out -i'n application" Sen;

No. 404t,'795,-'fi1ed Dec. 1907, to which reference may be had. The present "me-j out in the claims.

In the drawings :Figure 1 is an elevaloose member of a clutch. Also appro- .priately secured to the driving shaft to romember 4, said stopping arm 9 having 'a projectingportion 10,. adapted to contact 1 ine,vwhich may removed into. t

chanical embodiment of my invention is shown and described herein as applied to such general type of sewing machine but is obviously not circumscribed or restricted in this respectbeyond the limitations pointed tion of the present embodiment of theinvention, as applied to a sewing machine of the general character referred to, only so much of such machine being illustrated as desir-. able toshow'the. relation of the invention. thereto, and some parts being shown in section. Fig.2 is a detached detail of the channel guide and liquid supplying nozzle.

The driving shaft 1 is suitably supported upon a frame 2, and has loosely mounted thereona belt pulley 3, constituting the tate therewith is the fast clutch member 4,- the two members constituting the-friction clutch of usual form, being relatively movable u on the driving shaft 1 by a treadle c-ontro led-rod 5 to place them in driving or non-driving relation, .as will be readily un-- .derstood'by those skilled in the art, and as pointed out in my application herembefore mentioned.

' A spring 6 has 'oneend secured at 7 to the clutch member 4'. which is secured to rotate with the driving shaft,'an'd its other end socured at 8 to the initial stopping arm v9 loosely mounted upon the hub of the clutch with the stop-finger 11 when the latter is gitudinall of the stud 12 and is caused to .so move. y: means of a spring 13 actinguponan arm 14.- ;secured to a rocking sleeve 15, which in turn is connected to the sleeve 16 of the stop-finger 11, by means of arm- 17;

a'trea'dle rod l8 serving to move the stop- 100 'fing'er .11 inthe opposite direction as pointed -out. in the ap i .tionfled." v Y The face of the fast clutch member 4 is provided with astop '18, which, upon reverse1 5 cation hereinbefore men m'ovement-ofthe clutch member 4 under the recoil ofspring '6- is adapted tojfengagethe stop-finger 11 an bring the parts to rest in the desired predeterminedposition. 'br ake1 9 carried by the 'stopefingersleeve 16 0'] v e path-of said stopping arm 9. The stop-finger ll-is mounted to slide lonis caused to act upon the clutch member/t when the latter 1s engaged by the pro ecting portion 10 of the stopping arm 9. The parts so far described are and may be all as pointed out in the application hereinbefore mentioned and need no further description. i

'In the operation of the machine, the treadle rod 18 will be depressed and the stop-finger 11 moved from engagement with the parts 10 and 18, and the clutch members 3 and 4 will be placed in driving relation by means of the treadle rod 5. l/Vhen the machine is to be stopped, tre'adle rods 5 and 18 will be released, thus disengaging the clutch members 3 and 4, and the stop-finger 11' will' be moved by its spring 13 into the pathof the projection 10 of the stopping arm 9,

which will consequently be brought to rest.

Under the momentum of the machine the fast clutch'member 4: will continue to move in the direction of: the arrow, Fig. 1, until the increasing tension of spring 6 brlngs it to rest, whereupon the spring (Swill reverse the clutchmember 1 andthe machine parts connected to shaft 1,= until the' stop'18- on said clutchmember engages the stop-finger on the side thereof'opposite the projection 10, whereupon the clutch member 4' and shaft 1 will be brought to rest with the mapredetermined position. 2

The parts and the operation thus far-described are or-may be the same as in the application before mentioned.

Mountedupon a suitable bracket 20 secured to the machine frame is a tank 21 in whiehwater or other desirable moistening liquid may be placed. Connected. tosaid tank is an outlet 22, having'a tubular screw stem 23 engaged-by a screw nut 24, and containing an ordinary valve and itsoperating crank arm. To the lowerportion of the outlet 22 is connected a conduit 26 leading to a nozzle 27 preferably communicating with a passage way or opening 29 in the channel guide 28. The outlet end'of, this passageway or'opening is adjacent the lower end of the channel guide 28 so that water or other ligluid flowing thereinto from the conduit 26 w! 1 be directed into the channel of the shoe sole in advance of the awl and needle.

'Pivotally connected to the bracket 20'or other suitable part at 30 is a bell crank or other lever, one arm 31 of which is connected to a treadle' rod 32, the other arm 33 of which is connected to a valve crank 255% means of ailink 34. The connection of Ii 34 with the arm 33 is preferably made by a slot 35 in the arm 33 and a. set-screw or. pin 36', whereby the amount ofvalve movement and-consequent flow of liquid may be ad justed and regulated to the needs of the particularwork. From this construction it will be obvious that by means of the'treadle rod artisan without departing scope of the actual invent on as defined by opening said valve," an

32 the valve may be opened and closed inde-. jpendently of the machine operation.

Secured to the 'arm 33 of the bell crank lever is a valve closer 37. having at its end a toe 38 which, in thenormaloperationof" the machine in the direction 'of the arrow,

Fig. 1, rides over the cam 39 secured to the driving shaft 1, said cam having an abrupt end 40. A spring 41 connected to the valvecloser 3'Z and bracket 20 normally acts to depress the free end of the valve closer 37 so that after the machine has beenstopped and upon its reverse movement, the end 40 of the cam'39 engages the'toe 38 and moves tween the toe 38 and end of the cam 39v to permit movement of the valve closer 37 to the right, Fig. 1, byf neans of the rod 32 I to open the valve. valve may be made at the same-time as the machine is started, if desired, or may be opened later, because the treadle rod 32 is' not connected to the starting and stopping mechanism; and when once opened it may remain continuously open 'untilafter the stoppingmechanism acts and until the. ma-

chine is reversed, or it may be closed at any time by hand.

Owing to the independent 'treadle control of the, valve opening movement, it is obvious that such valve may be turned more or less to allow an amount of liquid to pass-through the conduit 'suitableto the work being done, and such regulation of liquid supply "is directly under control of the operative.

-While the particulars described are well suited as one mechanical-form of the invention, it is not to'be understood that these particulars; are essential sineefthe may be variously modified within the'sklll of the from the true the claims.

What I claim is:s-

1. Awork moistening'dev'ice, comprising, in combination, a source of liquid supply, a conduit leading therefrom to the work, means movedxby .theoperator for rendering said device effective for the delivery 'of liquid to the work, and power means, in

cluding a shaft, operative when theshaft is given reverse movement for closing said conduit.
